An original Arrol hydraulic riveting machine was unveiled at the Institution of Civil Engineers (ICE) Museum Scotland on the evening of the 27th March, in celebration of the 125th anniversary of the Forth Bridge being opened.
The riveting machine was designed by William Arrol to be used on bridge construction sites to give strong, consistent riveted joints. The riveter was suspended from a crane and could be used in a vertical or horizontal position. Power to drive the riveter was from hydraulics using compressed water. Riveters like this were used to drive home many of the 6.5 million rivets used to construct the Forth Bridge. Read this ICE leaflet for more information about the riveting machine.
The ICE Museum Scotland is housed in the Sir William Arrol Building at Heriot Watt University, Edinburgh and holds a collection of almost 400 items relating to civil engineering, including a number of items relating to Sir William Arrol and the Forth Bridge, including a one quarter scale model of a double cantilever skew-back from the Forth Bridge.
